Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, bearing 200 is installed on parts 100, and bearing 200 center is provided with axis hole 201.
A kind of two-stage bearing positioning device, comprises threaded rod 310, one-level nut 320, pushing tow bearing 330, tumbler 340, fixture 350, support 360, gasket ring 370 and backstay 380 that equal concentric is arranged.
Described threaded rod 310 is each passed through one-level nut 320, pushing tow bearing 330, tumbler 340, fixture 350, support 360, gasket ring 370 and backstay 380.Support 360 and gasket ring 370 are set up in bearing 200 both sides and conflict bearing 200 respectively.Described threaded rod 310 arranges fine thread.
Described one-level nut 320 is threaded with threaded rod 310, and one-level nut 320 lower end conflict pushing tow bearing 330.Rotate one-level nut 320, thus drive threaded rod 310 axial action.
It is described that tumbler 340 upper end contacts pushing tow bearing 330, lower end is threaded with fixture 350.During fine setting, rotate one-level nut 320, tumbler 340 is fixed, the setting of pushing tow bearing 330, reduces the resistance of tumbler 340 for one-level nut 320.
Described tumbler 340 comprises the secondary nut 341 and turning set 342 that are wholely set.Described pushing tow bearing 330 is embedded at secondary nut 341 upper end.Turning set 342 is the cylinder of hollow, and internal diameter is greater than the external diameter of threaded rod 310, and lateral surface is provided with coarse-pitch thread.
Described fixture 350 is sheathed on turning set 342, and comprise the three grades of nuts 351 and fixed cover 352 that are wholely set, described fixed cover 352 upper end arranges three grades of nuts 351, and lower end contacts support 360.
Described support 360 comprises cylinder 361 and plectane 362; Described cylinder 361 is the cylinder of hollow, and the internal diameter of cylinder 361 is greater than the external diameter of bearing 200.Described plectane 362 is circular flat board, and plectane 362 is fixedly connected with cylinder 361 at circumference place; Described fixed cover 352 is embedded at the center of plectane 362.
Described gasket ring 370 is the rigid annulus of hollow; The internal diameter of gasket ring 370 is greater than the external diameter of threaded rod 310, and the external diameter of gasket ring 370 is less than the external diameter of bearing 200.During work, gasket ring 370 is subject to the axial force of backstay 380, thus promotion bearing 200 moves axially to assigned address.The setting of gasket ring 370, increased lifting surface area, reduces the pressure of backstay 380 pairs of bearings 200, and when avoiding locating, this device is to the damage of bearing 200.
Described backstay 380 is threaded with threaded rod 310, and backstay 380 upper end contacts mutually with gasket ring 370.The cross section of backstay 380 is positive six shapes, convenient wrench rotational positioning bar 380.The axial length of backstay 380 is at least the twice of threaded rod 310 diameter, thus reduces the stressed of between cog.
Described cylinder 361 offers and observes groove 361a; Described observation groove 361a is strip, and is distributed in cylinder 361.Observe the setting of groove 361a, convenient when using this positioner, observe the position of bearing 200 on parts 100.
The external diameter of threaded rod 310 is less than the internal diameter of bearing 200.Threaded rod 310 is all separated with gap with tumbler 340, fixture 350, support 360, bearing 200, gasket ring 370, avoids threaded rod 310 to touch mutually with a tumbler 340, fixture 350, support 360, bearing 200, gasket ring 370.
During installation, first bearing 200 is tentatively installed on parts 100.Then threaded rod 310 is passed bearing 200.Threaded rod 310 upper end wears support 360, fixture 350, tumbler 340, pushing tow bearing 330 and one-level nut 320 successively, and lower end wears gasket ring 370 and backstay 380 successively.Spanner is sheathed on three grades of nuts 351, thus positioning mounting 350, be then sheathed on secondary nut 341 with another spanner, rotate tumbler 340, thus by tumbler 340 precession fixture 350.
The pitch of the coarse-pitch thread of turning set 342 is greater than the pitch of the fine thread of threaded rod 310.
During work, secondary nut 341 is rotated with spanner, tumbler 340 is made to screw out fixture 350, revolving part drives pushing tow bearing 330, one-level nut 320, threaded rod 310, backstay 380 and gasket ring 370 up to move, thus promote, near the quick assigned address arrived on parts 100 of bearing 200, to do at the beginning of one and locate.Then rotate one-level nut 320 with spanner, one-level nut 320 drives threaded rod 310, backstay 380 and gasket ring 370 up to move, thus accurate adjustment bearing 200 position on parts 100, locate complete.
The utility model is illustrated according to embodiment, and under the prerequisite not departing from present principles, this device can also make some distortion and improvement.It should be pointed out that and all drop on the technical scheme that all employings are equal to replacement or the mode such as equivalent transformation and obtain in protection domain of the present utility model.
